3. Essential Question: Standards:
How do we use the distributive property to simplify expressions?
Standards:
A.SSE.1 Interpret expressions that represent a quantity in terms of its context.
Interpret parts of an expression, such as terms, factors, and coefficients.
Interpret complicated expressions by viewing one or more of their parts as a single entity.

4. Vocabulary
The Distributive Property
Term
Coefficient
Factor

5. The Distributive Property
The process of distributing the number on the outside of the parentheses to each term on the inside.
Example
5(x + 7)
5 • x + 5 • 7
5x + 35

6. Examples 1. 5(2x+1) 2. -3(x +5) 3. 2 –3(x + 6) = 5(2x) + 5(1)

7. Which statement demonstrates the distributive property incorrectly?
3(x + y + z) = 3x + 3y + 3z
(a + b) c = ac + bc
5(2 + 3x) = x
6(3k - 4) = 18k - 24
Answer Now

8. A term is a 1) number, 2) variable, or
3) a product / quotient of numbers and variables.
Example 5 m
2x2

9. the numerical part of the term.
The coefficient is
the numerical part of the term.
Examples
1) 4a 4
2) y2 1 3)

10. Factor
Factors are numbers you can multiply together to get another number: EX. 2 and 3 are factors of 6, because 2x3=6 In Algebra, factors are what you can multiply together to get an expression.

11. Try the following on your own
(3 – x)
2. -2(x + 4) +3
3. 2(x + 6 – 3)

12. 1. 4 + 6(3 - x) 2. -2(x+4)+3 3. 2(x+ 6 – 3) = 4+ 6(3) - 6(x)

13. Homework 2x + 3(6x - 12) = 124 3x + 5(2x - 9) = 98
